PLANT CITY — Another possible sinkhole was discovered about 1 a.m. Tuesday near Interstate 4, this time at the eastbound exit ramp to southbound Alexander Street, according to the Florida Highway Patrol.

Unlike last week, all the interstate lanes are open and traffic is flowing around those closed exits.

A depression in the interstate at the same spot a week ago closed all but one lane for four days while crews pumped 1,000 cubic yards of concrete beneath the surface to stabilize it. All lanes were reopened Friday afternoon.

Several more sinkholes popped up throughout the week around the area, attributed to a drop in aquifer levels after heavy pumping by local growers trying to protect crops from a freeze.
